Grass Valley 8964 OMD (On Monitor Display) module

The 4−channel GV 8964 OMD (or on−screen display) board, which is based on the 8964 ENC SDI to NTSC/PAL Encoder
Module, mounts in the 8900 TFN−V Module Frame. In this application, each of the four channels can insert an 8−character
status mnemonic into a digital video stream and display the result on the analog output. Figure T−1 shows the status
mnemonic “CAMERA 1” inserted into one of the OSD board’s four video channels.
Each module frame can contain 10 modules for a total of 40 outputs per frame.

Each 8964 channel is associated with a particular Logical Output of the router. The source mnemonic is displayed as white
characters over a black background in the lower part of the screen.
The CM 4000 / AccuSwitch communicates to each Module Frame via the Jupiter LAN and a TCP connection.
The OSD also has the ability to display the current time on a separate line.
